I've owned two of the top pick air purifiers for 4 years now. They are powerhouses and I let them run 24/7, but they are basic in functionality and are more so set and forget.

I decided to give this one a try as it seemed to be a bit more modern, and had great reviews. This is definitely the higher end version of what I've been using. Being able to see my air quality charted probably isn't super necessary, but that doesn't mean I don't enjoy checking it. The best feature is likely the scheduling. Being able to adjust speeds by time of day automatically is an energy saver. Highly recommend.
